In this situation, ‘Est security’ found malicious code disguised as a ‘Corona 19 real-time status’ inquiry program and asked the public’s attention.
The malware found is an executable program (EXE) using file names such as ‘Corona’s domestic status’ and ‘Corona’s real-time corona status.’ When you run the file, you will see a pop-up window titled “Real-time Corona19 Status” depending on the variant.
The pop-up window shows four items and the corresponding numerical information, such as confirming patient, release (cure), death, and under test, as it shows actual corona 19 (coronavirus, COVID19) infection status. However, the malicious program automatically installs malicious code in the PC temporary folder without your knowledge.
Malware generated the PC has the function to perform the actual malicious behavior, and when infected, the user’s PC is exposed to various attacks such as ▲ remote control ▲ ▲ screen capture ▲ additional malware installation ▲ information takeover.
Est Security said that the program has a fixed number of all four items representing infected information, all at 100, and that the command control server (C2) uses a private IP address.
In particular, it has been reported that there have been no cases of infection reported through security’s public vaccine ”. However, the malicious program contains the actual RAT malicious module, so it cannot be ruled out that there is no possibility of threat of similar variants.
